This simulates a magnified view of a photo printed by a 4-colour printing press. In four-colour printing, like magazine photos, a picture is represented by tiny spots of only 4 colours of ink, in varying sizes of dots, cyan,yellow, magenta, and black. (Sometimes special spot colours are added, at extra cost, for instance a particular logo colour when it is important to get an exact colour match) The screen frequency, or the size of the spots of ink, is measured in dpi, or dots per inch. Typically, a higher number of dots per inch, like 240 or 300, is found in higher quality printing while a B&W newspaper may be 80-120dpi. This is where the term dpi comes from and originated well before digital photography. For a while at the start of digital photography the resolution of an image was also described as so many dots per inch but that was soon changed to the more accurate ppi, or pixels per inch.
